TL;DR: In this article, optical tweezers are used to create a local growth peak at the growing front, which is used to study the preferential incorporation positions of incoming particles, and the results show that the particles surfed with a strong Marangoni flow tend to fill the gap and smooth the steep peaks.

TL;DR: Coupling ratio, actual amplitude to nominal amplitude, can be calibrated by power spectral density during sinusoidal oscillations, and with oscillation frequency increasing, coupling ratio decreases in both x- and y-directions.

TL;DR: A convenient route to analyze the changes of RNA conformation and folding dynamics by combining optical tweezers with X-ray scattering methods is established and can be easily applied in the studies of other RNA structure and ligand-RNA.

TL;DR: In this paper, a micro-imaging-based method for measuring the particle size by utilizing an image grey scale was proposed, which is characterized by comprising the steps of photographing a discrete standard size particle image on a microscope, measuring distances of an intersection point between a grey scale distribution curve and a background grey scale horizontal line on the particle edge along an x direction or a y direction, gradually scanning the distances row by row/column by column, wherein a maximum value is the diameter of the image measured in the direction, scanning different out-of-focus areas along a

TL;DR: In this paper, the authors proposed a method to directly extract the orbital angular momentum (OAM) spectrum of light fields from a recorded single-shot speckle pattern by exploiting a scattering optical element.
